Description

[Detailed Description of the Invention] This invention relates to a water supply device that keeps drinking water fresh at all times in an emergency.

Conventionally, it was used as a drinking water storage tank in case of emergency.
There is one shown in FIG. 1 of Publication No. 714 (FIG. 4 of the drawings of the present application).

To briefly explain FIG. 4, a tank 33 is connected and fixed in the middle of the water main 31 via a pipe joint 32, an on-off valve 34 is provided at the bottom of the tank 33, and the pipe joint 32 is divided into a water supply channel 35 and a water supply channel 36, the water supply channel 35 communicates the water main pipe 1 on the water supply source side with the inside of the tank 33, and the water supply channel 36 connects the inside of the tank 33 with piping on the water tap 37 side. A through hole 40 is opened in a part of the wall surface 39 that separates the water supply channel 35 and water supply channel 36 from each other, and a through hole 40 is opened to communicate the rain water channel 35 and 36. The water in the tank 33 is replaced to maintain its freshness, and in case of an emergency, the drinking water stored in the tank 33 can be taken out and used using an on-off valve provided at the bottom.

However, this tank is installed on the piping between the water supply source and the hydrant, and as it has a structure in which the primary pressure of the water supply source is directly applied, it must be a pressure-resistant container and requires water piping work to install it. In addition, when you want to take drinking water outdoors in an emergency, you have to transfer it to a container, so especially in a disaster, you don't have time to transfer it, and you end up taking the drinking water out. I can't.

This idea solves the above problems and keeps the drinking water in the container fresh at all times by connecting the container on the secondary pressure side of the faucet body, and also allows the faucet body and container to be attached and detached. By making it portable, the purpose is to secure drinking water by making it possible to easily separate the container from the faucet body and take it out in an emergency.

The basic structure of this device is that a water supply chamber is provided inside the faucet body that has a valve mechanism for water supply, a pipe holder is provided that projects vertically into the water supply chamber, and the pipe holder is inserted into the water supply chamber. A hole and a through hole are provided, a straight pipe part having a flange of the discharge pipe is inserted into the insertion hole and the through hole, and this straight pipe part is rotated inside the pipe holding part via a guide for sealing and steadying. The extended end of this straight pipe part is supported movably, and the extended end of the straight pipe part is made to face the inside of a separately provided container through an opening, and a water supply pipe is connected between the opening part and the pipe holding part 8, and the water to be supplied is Drinking water in the container is stirred and circulated through the through hole between the water supply pipe and the straight pipe section, and water is supplied from the discharge pipe through the straight pipe section, and in case of an emergency, the water supply pipe can be simply removed. The main body of the faucet and the container are separated so that the container can be carried.

Hereinafter, embodiments of this invention will be described in detail based on the drawings.

As shown in FIGS. 1 to 3, an embodiment of this invention has a faucet main body 1 which has a water supply chamber 2 communicating with a water pipe and a water supply chamber 3 on the secondary pressure side through a partition wall 5 having a valve port 4. Compartment and its valve port 4
It has a normal valve mechanism part A in which a valve body 6 corresponds to the valve body 6, and the extended end of the water supply chamber 3 is provided with pipe holding parts 7 and 8 that open in the vertical direction in the figure. The discharge pipe 11 is inserted into the insertion hole 9 and the through hole 10 of both parts 7 and 8.
Insert the straight pipe part 12 of 1. Flange part 13 provided on the outer periphery
is rotatably held on the seat 14 of the tube holding part 7.

The seal 15 is installed inside the tube holding section 7 via a cap nut 16, and the guide 17 holds the straight tube section 12 inside the tube holding section 8 so as not to swing, and there are a plurality of guides between the seal 15 and the inner wall of the tube holding section 8. A fluid passage hole 19 is formed by the rib 18 .

The container 20 has a required volume made of synthetic resin or the like, and the extended end of the straight pipe section 12 is inserted into the opening 21 of the container 20, and a water supply pipe 22 with a large diameter is electrically connected to the straight pipe section 12. One end of the tube is connected to the opening 21, and the other end of the tube is detachably connected to the tube holding section 8 by means of a coupling, a universal joint, or other connecting fittings (not shown).

In this invention, when the valve port 4 of the faucet main body 1 is opened as shown in Fig. 1, the water in the water supply chamber 2 flows from the valve port 4 into the water supply chamber 3, and continues to flow into the pipe holding portion as shown by arrow P. 8, each through hole 19 of the guide 17, and the water supply pipe 22 leading thereto, and advance into the container 20 along the outer periphery of the straight pipe section 12 inserted into the water supply pipe 22. Due to the internal pressure, the drinking water in the container 20 is supplied to the outside from the open end of the straight pipe section 12 through the discharge pipe 11 communicating with the straight pipe section 12 as indicated by arrow Q.

Therefore, the drinking water in the container 20 is stirred internally each time the water is supplied.
Since the water is circulated and replaced, the drinking water always remains fresh.

Next, in the event of an earthquake, fire, or other major disaster, the connecting fittings of the opening 21 of the container 20 are removed in one operation, the water supply pipe 22 is separated from the opening 21, and the discharge pipe 21 is removed.
After removing the straight pipe part 12 and plugging the opening 21 (not shown), the container 20 is carried with it and quickly evacuated.

Since this invention is constructed as described above, it has the following advantages.

(1) The main body of the faucet and the container are connected by a water supply pipe so that they can be easily attached and detached, so if an emergency evacuation is required, they can be separated by simply removing the cap of the water supply pipe. In the event of a disaster such as a major earthquake, it is possible to prioritize and quickly secure the necessary drinking water.

(2) The outlet that supplies water to the container and the straight pipe that supplies water to the discharge pipe remain separated and face the container, so drinking water supplied from the faucet enters the container and then enters the container. Since the drinking water in the container is supplied to the outside through the discharge pipe while being stirred and circulated, it is possible to keep the drinking water in the container fresh at all times.

(3) Compared to conventional drinking water storage tanks that are fixed in the middle of piping and are directly exposed to the primary pressure of the water supply source, the container can be easily carried and placed on the secondary pressure side of the faucet body. By providing the container in the container, there is no need for a pressure-resistant container, and the portability of the container can be significantly improved by reducing the weight of the container.
